使用主题格式的表达式我正在尝试将多个相似图的格式设置为一个表达式,以便我可以更改代码的单个部分来更新所有看起来相似的图。但是,我很难将其实现为代码。我提供了一个最小的工作示例,展示了我希望绘图是什么样子以及我希望我的代码是什么样子,存储一段用于格式化的代码和每个绘图的紧凑代码。关于如何修改它以使其工作有什么想法吗?我正在开发 JMP 版本 15.2。
dt = New Table( "Minimal Working Example",
Add Rows( 400 ),
New Column( "X", Numeric, Set Values( Repeat( 1 :: 20, 20 ) ) ),
New Column( "Y", Numeric, Set Values( Sort Ascending( Shape( Repeat( 1 :: 20, 20 ), 1 ) ) ) ),
New Column( "Size", Numeric, <<FORMULA></FORMULA>

表达式处理功能强大,需要一些练习。 这是一个让您入门的示例,但您需要阅读 Eval()、Expr()、NameExpr()、Substitute()、Substitute Into() 等内容。
Names Default To Here(1);
//make a 5-column table
dt = astable((1::20)` || J(20,4,randominteger(0,20)));
//the x column will be the first column
xCol = column (dt, 1);
//the y columns will be the remaining columns
yColList = (dt << get column names())[2::ncol(dt)];
//write the graph builder script, wrapping it in an expression. Use _XXX_ format for things
//you'll be substituting later. Here, that is just the "y" variable for a particular graph.
gbExpr = expr(
dt << Graph Builder(
Variables( X( xcol ), Y( _Y_ ) ),
Elements( Points( X, Y, Legend( 8 ) ) ),
SendToReport(
Dispatch(
{},
"400",
ScaleBox,
{Legend Model(
8,
Properties(
0,
{gradient( {Color Theme( "White to Red" )} )},
Item ID( "Size", 1 )
)
)}
),
Dispatch(
{},
"400",
LegendBox,
{Legend Position( {8, [0, -1]} ), Legend Position( {0, -1} )}
)
)
);
);
//cycling through the items in yColList, we create a graph for each y variable vs the x variable.
//be sure to read up on Name Expr ( ), as it is needed here to prevent evaluation of the Graph
//Builder script... we just want the code itself... we don't want JMP to try to evaluate the code
//until after we've made the substitution.
for (i = 1,i <=nitems(ycolList), i++,
eval(Substitute( nameExpr(gbExpr), expr(_Y_) , expr(yColList[i])));
);
干杯,

回复:使用主题格式的表达式由于 X、Y 和 Color 变量根据我的数据发生变化的方式,这种方法效果不太好,但是我设法使用 JSL Quote、Eval Insert、Parse 和 Eval 找到了更接近我想要的解决方案:
// A theme format I could change for a gazillion of plots
formats = JSL Quote(
SendToReport(
Dispatch(
{},
"400",
ScaleBox,
{Legend Model(
8,
Properties(
0,
{gradient( {Color Theme( "White to Red" )} )},
Item ID( "Size", 1 )
)
)}
),
Dispatch(
{},
"400",
LegendBox,
{Legend Position( {8, [0, -1]} ), Position( {0, -1} )}
)
)
);
// How I would like each plot code to look like
Eval(Parse(Eval Insert("dt << Graph Builder(
Variables( X( :X ), Y( :Y ), Color( :Size ) ),
Elements( Points( X, Y, Legend( 8 ) ) ),
^formats^
);")));
